2 proposals for CKOV support
Proposal A• Table size 1,820 (W) mm x
1,010 (D) mm
Proposal B• Table size is 1,400 (W) mm x
1,120 (D) mm
Comment on Proposal A and B
1. More material, heavier in weight
2. No walk way between the wall shield and CKOV support
3. No one could get into the CKOV support area, can be argued as preventive from accident inside the CKOV support
4. Distance between the tracker and the front side of TOF0 is 405 mm
1. Less material
2. About 280 mm gap between the shield wall and CKOV support
3. In case of anyone falls down inside the CKOV support area, should have enough space to get him/her out
4. Distance between the tracker and the front side of TOF0 is 366 mm
